When you bid on a commercial job, and you go in at cents per sq ft, is that per night? How do you determine a monthly rate. This is for your average office cleaning jobs. What exactly is a fair price per sq. ft.

I can declare with confidence a fair price in Sante Fe NM will be significantly lower than downtown Manhattan, NY.

It depends entirely on the requirements of the job that's up for bids. As a small business owner, you should already have your costs and profits equation figured out. So what are the requirements of the bidder?
